Title: Control circuit of semiconductor laser
Inventor: SAKURAI TATSUAKI
IPC: H01S5/068
Filed: 1990-06-19
Abstract: PURPOSE:To make the life of a semiconductor laser long by a method wherein it is detected whether the light-emitting power in a laser control area has been stabilized and, after the power is stabilized, a control operation in the area is stopped. CONSTITUTION:A regeneration-power control operation is stopped only in a laser control area. The output of a counter 15 is input to a D/A converter 16 for a digital-to-analog conversion operation; a switching element 18 is set to ON via a second drive circuit 17. An electric current corresponding to the output of the counter 15 is made to flow to an LD 10 in addition to an electric current at a regeneration operation. One part of radiated light by the LD 10 at this time is photodetected by using a photodetector 11; a photodetected electric current of the photodetector 11 is converted into a voltage by using an I-V converter 12; the output of the I-V converter 12 is compared with a reference electric current Vref by using a comparator 19; according to a compared result, the light-emitting power is controlled to a power corresponding to the reference voltage Vref. When a prescribed condition is satisfied, a controller 1 stops a power control operation in the laser control area.

Title: Semiconductor device
Inventor: UCHIDA YUKIMASA
IPC: H01L29/06
Filed: 1981-10-09
Abstract: PURPOSE:To prevent the adverse influence to an MOS type circuit operation in the vicinity at the program time of a fuse element and a malfunction due to contamination ion after the program by forming an impurity region of reverse conductive type to a semiconductor substrate in the part of the substrate under the fuse element. CONSTITUTION:Minority carrier in paired carried generated in a silicon substrate 11 in programming due to current melting of a fuse element 17 is diffused to a peripheral circuit. However, since the lower part of the element 17 is isolated from an n-type silicon substrate 11 with a field insulating film 122 and a p type impurity region 19 and the region 19 is biased at the ground potential, the minority carrier in the paired carrier is absorbed by the region 19, thereby preventing diffusion to the peripheral circuit. Further, contamination ion does not diffuse externally from the insulating film on the region 19 or a guard ring 20.

Filed: 1996-06-21
Abstract: PROBLEM TO BE SOLVED: To simplify a memory test circuit formed on an integrated circuit part of an ASIC(Application Specific Integrated Circuit) or the like, which has a multiple port memory. SOLUTION: Test address signals TADs are applied to a shift means 19. The shift means 19, synchronizing with a clock signal CLK, sequentially shifts the test address signals TADs to subsequent stages. An output signal of each stage of the shift means 19 is applied to each address port A-AD and B-AD of a multiple port RAM 26. By synchronizing with the clock signal CLK, the test address signals TADs are sequentially updated to sequentially apply different addresses simultaneously to the address ports A-AD and B-AD of the RAM 26. Thereby, multiple ports of the multiple port memory can be tested by a pair of test address signals TADs.

Title: Data repeating installation
Inventor: KOBAYASHI SHIGEO
IPC: H04L7/00
Filed: 1980-11-19
Abstract: PURPOSE:To reduce the repeating delay and reduce the cost, by inhibiting the input by an abort sequence and by inputting a pseudo flag sequence by a flag sequence, in the data repeater which repeats a bit synchronizing signal. CONSTITUTION:A data repeating installation 4' takes receiving data into a bit buffer 48 as serial data still synchronously with the synchronizing signal extracted from data received from a terminal equipment 3 and outputs data in the bit buffer 48 in serial synchronously with the synchronizing signal of an MODEM. If the frequency of the synchronizing signal extracted from receiving data is higher than that of the synchronizing signal of the MODEM, the input of the bit buffer 48 is inhibited temporarily when an abort sequence is issued from the terminal equipment 3. When the number of bits of data stored in the bit buffer 48 is decreased to a prescribed number, the data input is restarted. If the frequency of the synchronizing signal extracted from receiving data is lower than that of the synchronizing signal of the MODEM, a pseudo flag sequence is inputted to the bit buffer 48 just after a flat sequence is transmitted from the terminal equipment 3, thus absorbing the frequency shift.
